METAL SURFACE TREATMENT COMPOSITION HAVING EXCELLENT SLIP RESISTANCE, AND METAL MATERIAL TO WHICH SAME IS APPLIED

Abstract:

The present invention relates to a chromium-free metal surface treatment composition comprising 10-30 parts by weight of a silane-based compound, 0.5-6 parts by weight of an organic acid, 0.1-3 parts by weight of a vanadium compound, 0.1-3 parts by weight of a magnesium compound, 0.5-3 parts by weight of a wax and a balance of a solvent. The metal surface treatment composition of the present invention can ensure slip resistance and required properties such as corrosion resistance and workability, thereby enabling a metal material to be prevented from slipping or falling off during processing, pipe making and the like.
